336  * folio_dup_file_rmap_ptes - duplicate PTE mappings of a page range of a folio
337  * @folio:	The folio to duplicate the mappings of
338  * @page:	The first page to duplicate the mappings of
384 	 * don't allow to duplicate the mappings but instead require to e.g.,  in __folio_try_dup_anon_rmap()
423  * folio_try_dup_anon_rmap_ptes - try duplicating PTE mappings of a page range
425  * @folio:	The folio to duplicate the mappings of
426  * @page:	The first page to duplicate the mappings of
428  * @src_vma:	The vm area from which the mappings are duplicated
435  * Duplicating the mappings can only fail if the folio may be pinned; device
439  * If duplicating the mappings succeeded, the duplicated PTEs have to be R/O in
443  * Returns 0 if duplicating the mappings succeeded. Returns -EBUSY otherwise.
571  * fork() to duplicate mappings, but instead to prepare for KSM or temporarily
689  * Cleans the PTEs of shared mappings.
